GN 890 Pneumatic toggle clamps for push-pull clamping, with magnetic piston


Product description


The working principle of the GN 890 pneumatic toggle clamps is identical in construction and dimensions to the manual toggle clamps GN 842.

To ensure an ex-tended life of the mechanical parts aas well as the air cylinder, the operating pressure should not exceed 6 bar. In addition a lubrication control unit should be mounted in the air in-feed line. The sturdy mounting frame for the cylinder has been designed to avoid the trunions of the cylinder to protruding over the frame.

GN 890 pneumatic toggle clamps are also available as from size 360 as version M (with magnetic piston). In conjunction with a proximity switch (GN 896.1 / GN 896.2) the position of the piston is sensed and the generated signal can be used in sequence control systems.
